Reader MojoKid writes: If you're a Windows 7 or Windows 8 user who hasn't yet upgraded to Windows 10, you've probably been bombarded at some point by Microsoft to upgrade, and not always at the most convenient times. Such was also the case with one meteorologist who saw a Windows 10 upgrade prompt show up during a very inopportune time -- right in the middle of a live forecast. Metinka Slater, a meteorologist with Des Moines CBS affiliate KCCI 8, was going about her business, giving viewers a rundown of the 12-hour rainfall totals in the area when a nagging Windows 10 upgrade screen popped up, just like it has for thousands of everyday Windows users. But rather than get flustered or give into Microsoft's demands, Slater laughed off the annoyance. "Ahh, Microsoft recommends upgrading to Windows 10. What should I do?" Slater joked. "Don't you love when that pops up?"From the looks of it, either the concerned computer is running Windows 98, or is using classic theme.
